Saw vise



Patented Nov. 1, 1949 STATES ei'T-Nfr orsi The present invention pertains to a novel saw vise for securely holding a saw while it is being led yor Set.

The principal object Eof the invention is to iprovide la simple and inexpensive device of this character and one that is eiectiv-e in use. There is provided a fixed plate and a clamping plate movable relatively thereto. The movement of the clamping plate -iS secured from a shaft carrying an eccentrically mounted block which is fastened to the clamping plate through the fixed plate. Thus rotation of the shaft displaces the clamping plate relatively to the Xe-d plate.

Another object of the invention is to provide a simple dual str-ucture of the character set forth. In this embodiment of the invention there is provided an angle bar representing the xecl plate land having a clamping plate slidably supported externally along each side thereof. As in the rst construction, there is provided a shaft Within the yangle bar, and the shait carries pairs of eccentrically mounted blocks. One block of each pair is attached to one of the clamping plates by rivets passing through the adjacent side of the angle bar, and the other block of each pair is similarly attached to the remaining clamping plate. The angle bar is preferably so positioned that the saw m-ay be inserted vertically or horizontally, as desired, and the shaft is readily ad justed until the corresponding clamping plate is brought to clamping position.

The invention is fully disclosed by way of eX- ample in the following description and in the accomp anying drawings in which:

Figure 1 is a perspective view lof the device;

Figure 2 is an elevation at the open side;

Figure 3 is a section on the line 3-3 of Figure 2;

Figure 4 is a perspective of a modication; and

Fig-ure 5 is a section on the line 5-5 Iof Figure 4.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In Figure 1 is shown -a suitable table I o which the vise is supported by vertical legs 2 in a manner presently to be described. In the upper ends of the legs is rotatably mounted an operating shaft 3 carrying at one end a crank 4. The body of the vise comprises an angle bar 5 lying between the legs 2 and having one side vertical and the other upward and horizontal as shown in Figure 3.

'Ihe angle bar is held ina xed position on the shaft by the means shown in Figure 1. This suitable base and spaced apart to form a cli-annel. The inner or vertical sides of the members 1 lare apertured at 8 and between them is mounted the lower end of Ia post 9 carrying bolts I0 that may be fastened adjustably in the lapertures 8. A rod I I has one end attached to one of the collars 2l to be described and its other end is fitted with a clamp I2 adjustable on the post 9. By adjustment of the post 9 along the members I and adjustment of the clamp I2 on the post, the angular postion of the angle bar 5 is determined and xed.

lOn each of the sides of the angle bar `5 is attached a clamping plate I3 along one edge by rivets I4, with spacers or washers l5 mounted on each rivet between the parts 5 and I3. Along its `other edge, each plate I3 carried a row :of bolts I6 passing slid-ably through the adjacent lside of the angle bar 5, for a purpose thatI will presently be described.

The shaft 3 carries a number of eccentrics I'I mounted thereon in spaced relation and secured thereto. On each of .these eccentrics is mounted a pair of blocks I8, I9, the former being attached to the bolts I6 of the vertical side of the angle bar 5, Iand the blocks I9 attached to the bolts I6 of the horizontal side of the angle bar. The bar 5 is further supported by angle brackets 29 attached thereto along its length and also fastened to collars 2| mounted on the shaft 3.

In the use of the device, the saw 22 to be I'lled is inserted beneath one or the other of the clamping plates I3, according to Whether it is desired to lay the saw vertically or horizontally. The saw is inserted along the edge of the particular plate I3 that carries the bolts I6, as this is the yielding edge. The crank 4 is turned until the saw is clamped by the adjacent plate I3. It is evident that the mounting of the blocks I8, I9 permits either of the clamping plates I3 to be brought to clamping position.

In the modification shown in Figures 4 and 5, there is provided a channel body 25 and a clamping plate 26 along its lower surface. One edge of the clamping plate is attached loosely to the body by a series of bolts 21, with spacers 28 inserted between the plate and the body. The plate further carries rivets 29 passing slidably through the bottom of the body 25, for a purpose that will presently appear.

The edge of the plate opposite the spacers 29 is bent slightly at 30. Extending to one side of channel body 25 are fixed blades 32 adapted to 3 be driven into tree stumps or the like for supporting the device on the job.

A shaft 33 is suitably journalled lengthwise in the body 25 and carries a series of spaced eccentries 34. On each eccentric is mounted a block 35 into which the rivets 29 are secured. Thus, as the crank 36 on the shaft 33 is swung, the blocks 35 will be raised or lowered and the clamping plate 26 moved with them. The saw 3l is clamped, obviously by drawing of the bent edge 4 and movably supported thereon, a shaft along the other side of said xed plate, an eccentric on said shaft, and a block on said eccentric and attached to said clamping plate through said xed plate, said clamping plate having one edge attached loosely and spacedly to said fixed plate.
